My rearend just started poping when I accelerate and turn. I pulled rear ds to get home. I have 2002 sport 35s with 410 gears Trac-loc 44. I want to lock it. What should I expect to buy besides the locker kit. Do any kits come with spider gears or eliminate the trac-loc? I would not mind open diff w/locker. I know there is no cheap way to do it right. What is my best cost efficient reliable options? Thanks.
